Pretty cool! The SEFCU arena’s fire alarm system reminds me of something I’d see at Bridgewater State College! As I’ve mentioned, they have a whole variety of Simplex systems from the 1990s and present, as well as a couple from the 1970s.
As for the whole addressable system set up in a non-addressable manner thing, that reminds me of the Rondileau Campus Center at Bridgewater State College. I didn’t see the panel (odds are it’s a Simplex 4100), and despite it being addressable, only a couple of areas have addressable devices! They have a Simplex-rebranded SAE graphic annunciator underneath the 4603-9101 LCD annunciator that shows the zones:
The pulls in most of the building are Simplex 2099-9756 dual-action T-bars, and they have almost NO smoke detectors (some areas do have old Chemtronics heat sensors left over from the old Standard system; not sure if they still work). The signals in most of the building are 4903-9219 horn/strobes. But the cafeteria, the student life office/lounge and the music/theater department has 4099-9003 pull stations and addressable TrueAlarm smokes (the signals are non-addressable TrueAlert horn/strobes in these areas).
BTW, regarding the Science Library, it’s interesting how they obviously had to put in Notifier pulls and smoke detectors so they could be compatible with the existing addressable Notifier panel. I’m also not surprised that they used SpectrAlert Advance horn/strobes, as lately (since around maybe 2003-2004), Notifier prefers using the SpectrAlert signals instead of Wheelock. The Notifier system also sticks out, in contrast to how all the other academic-related buildings have Simplex systems.
And another thing about the arena, I suppose if they wanted to make it more up to code, they could simply put Wheelock RSS strobes next to many of the LifeAlarm speakers, and install the same strobes in the gym as well, and in some areas where installing a remote strobe wouldn’t be practical, replace the LifeAlarm with a Wheelock E70 or something. Since the 4903-9101 you mentioned is not ADA-compliant, Simplex would probably put the speaker on a new strobe plate, or replace that alarm altogether.
Interesting to see them use the 4251 pulls in a 1992 installation, as I recall the 2099-series pulls first came out around 1991 (according to a datasheet I found on them). Maybe Simplex had a lot of 4251 pulls left over in stock and decided to put them to use?
